On Scintillation of Radio Sources

Abstract

In a communication concerning scintillation of discrete radio sources and geomagnetic activity, relative to transit observations (within 45° of zenith) Slee (1962) found correlation between scintillation and geomagnetic indices. Scintillation activity was assessed as low if none of the radio sources showed detectable scintillation or if scintillation occurrence was isolated and high when all sources exhibited intense scintillations for several hours during the night.
